Summertime Key Lime Buttercream & Coffee Frostings

Two new frostings this week!
First - Key Lime Buttercream which I have been wanting to try for a long time. So easy....
Ingredients
8 tbs of unsalted butter at room temp
3-4 tbs of Nellie & Joes Key West Lime Juice
or you could use a fresh lime
Zest of a lime (2 tsp)
5 cups of sifted confectioners sugar

Beat the butter and lime juice in a bowl and then add the sugar gradually. Start with just 2 tbs of lime juice and add gradually.

The recipe I saw added coconut to the tops of the cupcakes which were vanilla.
I'm pairing this frosting with a devils food cupcake. Yes the frosting is white and no I will not be putting food coloring in. But I did give in and sprinkled some pale green sugar crystals on them. For the store - I will be posting a little sign as I don't want people to think they're biting into a vanilla cupcake!
The results? I liked this a lot. It was tangy and I would add a bit more lime zest the next time. I would have loved to have added the coconut but maybe next time. I just need to introduce these new flavors slowly.....
Almost forgot - this frosted just about 18 mini cupcakes but I pipe a LOT of frosting on each little cake.

Next on the menu is Coffee Buttercream

10 tbs of butter at room temp
1 tbs of milk at room temp
2 tsp of instant espresso disolved in a small amount of water and cooled
3 1/4 - 3 1/2 cups of powdered sugar
In a bowl mix all the ingredients until smooth gradually adding the sugar.
The results for #2? I love this frosting & think it would be great on a chocolate or vanilla cupcake. Mmmmmm with a glass of Iced Coffee! (if you are reading this Erin - you owe me one the next time you visit!)
A pix tomorrow of this...

Let me know if you try either of these and what you think.
